Specification of Letters Patent.

Patented Jan. 8, 1907.

To all whom z'tlmwy concern:

Be it known that I, HE BER A. Braces, a

citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Im rovemnts in Type-Writing Machines, of w 'ch the following is a'full,

clear, and eziact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to type-writing ma- 7 chines, and has special reference to improvements in machines of this character designed to provide a writing-in-sight machine having special features insuring great speed and ease o manipulation. 1

To. this end the invention contemplates certain practical improvements possessing special utility in connection with a writingmachine'of the front-strike typeand inclu ing in' its general organizatlon a travelmg type-carriage carrying the printing mstrumentalities and a traveling paper-carriage carrying he platen, its auxiliaries, and also carrying. he ribbon mechamsm. The urpose of the invention in this connection is to provide means for dividing between'thetwo carriages the travel necessary to get from the final letter of one the mac 'ne whereby the operator can, from the keybo'ard and without removin his hands therefrom, actuate and contro the movement of both carriages and also the letter spacing mechanism, the hne-spacm mechanism, and the rlbbon mechamsm, al

I i of which contribute materially to carrying out the general thought of the invention.

With these and many other ob ects 1n view, which will be more readil apparent as the nature of the invention is etter understood, thesame consists in the novelconstruction,

rinted line to the initial letter of the next printed line, thus effecting a.

combination, and arrangements of parts sco e of the invention; but'a preferred em'-' bo iment thereof is shownin the accompanying drawings, in which a Figure 1 is a top lan view of a type-writ ing machine 'embo ying the present inven-' tion.

Fig. 14 is a detail view of the rear part of the typehanger, showing more clearly the ivotal mountin of the t e-barsthereon. g ig. 15 is a detai sectiona view on the line 15 15 of Fii v 3 I 'ke reference characters designate corresponding parts in the several figures of the awings. The improvements contemplated b the present invention are specially applicagle to a type-writi machine wherein the papercarriage and't e type-carriage are connected lines. p

to move in opposite directions, preferably in unison and in the direction of letter-spacing, whereby a division of the travel may be fproperly'apportioned to each carriage toe ect a saving in time and space required to get;

from the final letter of one printed line tothe initial letter of the next printedline. As the improvements centeraround this combination, reference will first be made to the relative mounting, of the paper-carriage and type-carriage. The term .paper-carriage term type-carriage is employed to de- 1 designates the main horizontal base scribe the traveling carriage with the. printing instrumentalities supported and carried therebyi. e., the type action, which includes the key connection and the auxiliary devices.

As indicated in the drawings, the numeral ortion of the machine, provided, preferabl y at the back thereof, with an upright elevated base-section 2, supporting thereon at the top the opposite paral el elevated track-rails 3, u on which travel the front and rear trave er-rollers 4 and 5, respectively, of the frame 6 of the traveling paper-carriage, (designated in its entirety by the numeral 7.)

' The main horizontal base portion 1 of the machine has suitably supported thereon the front and rear rail sections or members 8 and 9 held at a slight elevation above the floor of the base and accommodatin for travel thereon the front and rear trave er-rollers 10 and 11, respectively, of the frame 1.2 of the traveling type or type-action carriage, (designated in its entirety by the reference-number'13.) Thus both of the carriages 7 and 13 have independent traveling supports upon se arate parts of the base, and in the preferabl e construction, as illustrated, the traveling papercarriage 7 is supported for movement in ahigher plane than the type-carriage 13 to insure perfect visibility of writing, as will hereinafter be more fully a parent.

To provide for coup ing'the two carriages together for movement in unison, and yet in opposite directions, there is associated with the paper-carriage 6 a rigid coupling member 14, which is preferably in the form of a triangular frame centered with reference to the paper-carriage frame and pendent therefrom Within the elevated base-section 2, as ma be plainly seen in Fig. 5 of the drawin s. his rigid pendent triangular couplingame 14 carries at its upper end or apex a connectingyoke '15, cooperating with a grooved collar 16 upon acenter rod 17, arranged longitudinally of the paper-carriage frame 6 and forming a part of the frame structure. At the bottom the rigid couplin -frame 14 carries as a'base member thereof a ottom slide-rod 18, working in the stationary guides 19, arising from the horizontal portion of the base, and

to the opposite extremities of the base part of the coupling-frame14 are attached the ends of the separate flexible draft-tapes 20 and 21, which have their other terminals re spectively attached to diametrically opposite points on a common actuating-drum 22, arranged horizontally over the base and having a vertical pivotal mounting23 thereon. This common actuating-drum 22 has separate peripheral tape-seats 24 and 25, ar-

ranged in diflerent horizontal planes to correspond to the difierent horizontal planes of the draft-tapes 20 and 21, connected with the pendent cou ling-frame 14 of the paper-carriage. Simil ar to the arrangement and connection of the said draft-tapes 20 and 21 like tapes 26 and 27 are respectively connected to theseparate portions of the actuating-drum at diametrically opposite points and to the opposite ends or sides of the type-carriage frame 12, as indicated ata in Fig. 6 of the drawings. This arrangement provides a positive coupling connection between the earriages, whereby the same move simultaneously in opposite directions, and the papercarriage will in the particular embodiment of sion-regulating escapement 30, whereby the 5 tension of the spring may be regulated to provide the desired tension for the machine.

.The travel of the type-carriage 13 to correspond with the length of the line to be written is controlled through the medium of the oppositely located marginal sto s 31, arranged, respectively, at opposite sides of the transverse center of the base and disposed beyond opposite sides of the type-carriage frame 12. Both'of these marginal stops are referably in the form of upright posts standmg above the base and having their stem portions adjustably and slidably mounted in the margin adjustmentslots 33, provided in the base. With each of the slots 33 is associated a scale-plate 34, preferably havinggraduations upon both sides of the slot, with the lines of the scales alternating, so as to permit a coarser and more legible scale than if a single scale were employed. The stem portion of each mar inal stop has associated therewith a suitab e ratchet locking device 35, cooperating with a catch-rack 36, fitted on the base beneath each margin slot and providing means, in connection with the device 35 whereby each stop may be locked in any adjusted position, according to the extent of travel to be given the type-carriage.

Referring to the general features of the traveling paper-carriage 7, it will be observed that the carriage-frame 6 is of a general rectangular form and is provided at the op' site ends thereof with the upright verticallyslotted guiding-standards 37, loosely accommodating therein the spindle ends 38 of the roller-platen'39, to which spindle ends are fitted the usual knobs for manipulating the platen in the ordinary way. The rollerplaten 39 is provided at one end thereof witha ratchet feed-disk 40, constituting a means must be'associatedwith the platen to provide for adjusting the position thereof, ac-

cording to whether upper or lower case characters are being printed, the invention contemplates the employment of a counterbalancin v device serving to nearly counterbalance t e weight .of the platen to ease the lifting action thereof. This counterbalancing device comprises the rock-shaft member 41,

arranged longitudinally of the carriage-frame 6 and carrying. at opposite ends thereof the rocker counterbalancing-arms 42, extending forwardly from" their connection with the shaft 41 and having their extremitiesdisposed beneath the spindles-38 of the laten.

A counterbalancing-spring 43 is suitab ycon--.

nected with the rock shaftmember 41 or other convenient part of the counterbalancing device to provide for normally exerting an upward i g te dency upon the platen f r the purpose indicated. Y l

Referrin to the means employed for eflecting the shi action for the p aten, commonly termed the shift-key action, it will benoted that the lifting connections for the platen its angle a yoke 46, coupled on a collar 47, mounted on a frame-rod 48, fitted lon itudinally inthe paper-carriage frame. t: the extremity of its pendent armthe bell-crank lever 44-carries an engaging roller 49, which rides upon a bearing-rai two shift-key levers 55 and 56, Fig. 1, -arranged, respectively, at opposite sides of the keyboard and carrying the usual operatingkeys which constitute apart of the key.

For convenience 1n describing the During this ver 55 the stud 57 engagesthe inclined or "camming. surface of the latch 59-, pressin 50, connectingthe? rearextremities 'of the side arms 51 of a vertically swingingor oscillating lifting-frame 52, and the bearin rail part ofthis lifting-frame is normally he (1 inposition for engagement.

action ofthese se arate key-levers 55 and 56 the same will be escribed respectively, as the left-hand and right-hand shift-key levers.

The left-hand shift-key lever 55 and preferably the left-hand sidearm 51 of the liftingframe 52 are provided with outwardly-prof jecting catch pins or studs 57 and 58, with which cocperates a recessed hook-shaped latch 59,having a beveled upper end or nose, against which plays the in 57 on the shift key lever 55. A somew at similar latch 60 codperates with similar catchpins 61 and 62 projecting from the right-handshift-key'le-- ver 56 andv referably from theJ'i ht-hand side arm of file lifting-frame 52. he latch 59 is primarily a releasing-latch, and the latch 60 is a locking-latch; Both are rigidly mounted on a pivotally-hung rod 63, which also carries an arm 64, to which is connected oneend of a coil-spring 65. The opposite end of the spring 65 is connected with the frame of the type-carriage. The spring 65 thus holds'the latches59 and 60 toward and against the catch-pins on the shift-key levers and liftingframe.

Beferrin to-Figs. 1113,'-the position of the parts a ove'described when the platen is.

in lower-case'position is shown in Fig. 11

with the studs 58-and: 62 in the recess of the latches 59'and 60, res ectively, whereby the platen is firmly locke in its normal or'lower case osition. In-order to temporarily lift thep aten t'o upper-case position when it is desired to strike a capital letter, the shift-'key on the left-hand shift-key lever 55 is depressed. The lever 55, engaging with the pressthe front end of the lifting-frame-and elevate the latch to upper-case. position.

ownward movement of. the leit back and holding it and the latch 60 out 0 TOO- 4 side-arm 51 of the lifting-frame 52, will decomprise a bell-crank adjusting-lever 44, piv-, oted at one end, as at b, Fig." 5, to-the' front] bar of the paper-carriageframe and having at 1c 5 engagement with the studs 58.'and 62, as

shown Figfi'12. U on releasing the ressure on the s ft-key t e weight of the p aten and its connected parts will cause it to return to lower-case position. and the parts just described will return to their normal position, as shown in Fig. 11. When it is desired to lock the carriage in up er-case position, the shift-key on the ri htand shift-key lever 56 is depressed, an the engagement of the lever '56 with the lifting-flame will carry. down the front end of the latter and elevate the platen.

} During-this movement the lever 55 will remain at'rest, and the stud 61 on the lever 56 will engage the cam be thereby ming-surface on the latch 60, andboth latches wil pushed back, sothat when the stud 61 clears the point'of the hook on the latch 60 the latches Will be thrown forward by the spring 65, carryinglthe hooks over the studs 58, 61, and 62, as s own in Fig. 13. The platen will thus beheld in. upper-case position until reing-frame; but it is obvious that the latch 60 alone will also serve this purpose by the engagement of the stud 61 on the shift-key lever '56- with the upper hook member of the latch 60. 1 5 Reverting to other parts carried by the pa- 'p'er-carriage 7, it will of course be understood that the same is equipped with suitable paper guiding and holdin means for guiding the paper toward and a out-the platen, and, as shown, these auxiliaries may be directly associated with the platen or roller itself, so as to be removable therewith from the main part of. the frame 6 without disturbing the position of the latter on its track-rails 3. In 2 5 this connection the roller-platen 39 is illustrated as being arranged within an open casing 66, having end plates and supporting the paper-guides 68. Also the casing 66 has mounted therein above the plane of the roller 0 'a longitudinally-disposed sup) ortingrod 69,

upon whichmay beadjusta 'rality of pa er-clamps. v

Each of t e paper-clamps comprises a collar 70, slidable upon the rod 69 and held to y fitted a plu- 3 5 any, adjusted position thereon by'the sets screw28, assing through a threadedopenin in the col ar and bearing against a flattene side of the rod 69, as plainly shown in Fig. 4

' of, the drawings; also, a pair of pendent inner 0 and outer spring-arms 32 and 45, res ectively, the inner of which is provided" wit an opening through. which is yieldingly pressed the aper-holdingroller 67, journaled u on the Eee end of the outer spring-arm'45. he

. 4.5 "set-screw 28isformed with a shoulder bearing against the outer member or arm and serving to set the roller 67 against the platen.

Usually the inner and outer arms 32 and 45 ing the pa er 1n connection with the platen 39, yet t e construction shown and described provides a convenient and compact 6c .mountingQOf the roller and its auxiliaries Within a common casing which is removable and replaceable as an entirety with reference to the guiding-standards 37 of the paper-carria e frame 6. j

he paper-carriage frame 6 has. offset from when tightened serve to clamp therear ortion thereof a rearwardly-projected ob hque bracket extension 71, upon which is supported the ribbon mechanism as an entirety, whereby the entire ribbon-carrying mechanism is carried with the'papercarriage. This ribbon mechanism in its general organization embodies the oppositelyarranged ribbon-spools 73, loose upon the spool-posts 74. These posts have loosely mounted thereon sleeves rigid with crowngears 76 and carrying binding-nuts 75, which the .spools fast to such crown-gears 76. Each crowngear 76 meshes with a pinion 77, carried by a motion-transmitting s aft 78, journaled in suitable bearings 79 upon the bracket extension 71 and carrying at an intermediate point a driven beveled pinion 80, meshing with a complemental inion 81 ,carried on the stubshaft 82 of a ro ing operating-gear 83, which rides upon the surface of the tripping-gear platform or table 84. This tripping-gear platform or table84 of the ribbon mechanism is normally held in a horizontal position in contact with the periphery of the gear 83 and is pivotally hung, as at 85, upon a stationary bracket 86, carried at the u per end of the elevated base-section 2. Sai pivotal tripping-gear platform 84 hasconnected thereto the upper end of an adjusting-rod connection 87, the lower end of which is pivoted to a rocker-arm 89, carried at the rear end of an o erating rock-shaft 90, journaled in bearings heneath the base 1 of the machine and having attached to the front extremity thereof an operating-arm 91, carr g an engaging roller 92, coperatingwit a combination movement-controllin key 93 ,the ac tion of which will be resent y referred to.

. Theribbon R win s and unwinds from one spool to the other, according to which is fast or loose with its crown-gear, and is arranged through the medium of suitable guides to pass entirely about the roller-casing 66 and have its operative portion extend longitudinally of the platen in front thereof, as may be plainly seen from the drawings.

The actlon of the movement-controlling key, in conjunction with the ribbon mechanism just described, bears a 006 erative relation to the type-action itself, w ich will now be taken up.

The type-carriage frame 12 is provided at the top with a horizontal. type-basket opening 94, which is open throughout at the front, rear, and top, whereby absolute visibility of writing may be, provided for, and hence said type-basket opening 94 provides for the arrangement therein of a horizontal. typebasket made up of a semicircular series of type-bars 95, normally lying in substantially horizontal positions and striking-against the front side of the platen in the manner that is commonly known'in the art as front-strike v writing-in-sight machines. The individual type bars 95 carry a Iplurality of t e-faces U or L, representing t e upper and ower case characters, and are associated with a hanger ring or segment 98 mounted in an upri ht 5 position within the rear of the type-has et opening 94 of the type-carriage frame. The hanger-ring '98 has extended from the top side' thereof a bifurcated finder-guide 99, within which each type-bar passes, so that it is brought with accuracy. to the common printing-point. To rovidefor the hanging of the series of typears 95, the upright seg ment hanger-ring 98 is provided in the pe ripheral edge thereof with a plurality of radlal type-bar slots 100 and a ivot wire or rod 101, suitably fitted within t e body of the ring and intersecting the several slots 100. At its rear side the hanger ring or segment 98 has yiel'dingly mounted thereon a retainingplate 102 ofa segmental form, Fig. 14, and preferably sup orted on stud-screws 72, between the hea s of which and plate 102 are inter osed the coil-springs 97, which permit the p ate to yield outwardly when the typebars are inserted or removed. The function of this yieldingly-mounted plate 102 is that of a retainer for keeping the type-bars in o erative' osition within the slots 100 upon t e pivot w re or rod 101, while when it is desired to remove or to re lace any one of the typebars the plate wil' yield sufficiently to ermit the type-bar to be lifted ofi or placed in position on the pivot-rod lOl. i Below the horizontal plane of the rin 98 is arranged a slotted guide-bar 103, and elow the plane of the slots of the latter is arranged a stationary fulcrum-rod 104, the function of which parts will be ap ment in connection with the mounting of t e, type-action arts. However, at this \point it may be notec that the shift-key levers 55 and 56 are provided at their rear ends with the pivot-hooks 105, which are loosely held in engagement with the fulcrum-rod 104 through the medium of adjustable supporting-spring 109, interposed between the said levers and a spring-supporting bar 107, mounted across. the typecarriagle, frame, within the bottom portion thereof. j I

The type-action per se-includes a swinging type-bar 95,prov1ded at its heel with an open pivot-hook 108, detachably engaging the pivot-wire 101 of the hanger-ringworking in a radial slot 100, Fig. 4. To the, heel for the ready disconnection of the link 1 10,v

while at the same time maintaining the said parts plvotally connected in their normal re- 6 5 lation but a preferred construction is shown mediate the ends of the latter.

of the type-bar,behind-th'e pivotal point 101,

keyhole-slot 106 in the link 110 is brought into registration with the key 111 i and then passed over thejkey, after which a partial turn of the link 110 causes the keyhole-slot to be thrown out of alinement with the key 111, and hence serves to maintain the parts in interlocked relation, .though readily de tachable. g

The arms 88 are preferably formed with the ull-bars 112 as an integral part thereof. In ig. 7 is illustrated one of the central type-bars and operating-keys. The pullbars and key-levers are arranged in honzontal planes, and as the type-bars are segmem tally mountedprovision must be made for the varying distance between the pull-bars and type-bars. This is accomplished by increas ing the length of the. arms 88 as their positions approach the sides of the machine, and in order to avoid any torsional pull upon the type-bars each arm is projected vertically until it intersects the plane in which its '0 e,-

bar swings and is then offset or bent into t p at plane, so that the lplull on each type-bar. is even and true. T 's construction is illustrated most clearly in Fig. 14. i

The rear end of thepull-bar 112 loosely works through one of-the guide-openings of the slotted guide-bar 103 and the front end of the pull-bar is pivotally connected to one end of a swinging toggle-link 113,- whose other end is pivoted to a key-lever 114 inter- Intermedi' ate its ends the said swinging 'toggle1ever 113 has pivotally connected thereto one end 1o 5 -of a short fulcrum-link 115, having an open with said rod 117 by the retaining-rod 118. rrp I The point of connection between the toggle links 113 and the fulcrum-links 115 and the length of the fulcrum-links, as will be understood, will vary slightly to compensate for the varying. lengths of the key-levers for the 1 i 5 different banks of keys, the length of the fulcrum-links' being less and their point of connection lower for the longerkey-levers'.

The rear end of the key-lever is removably hooked under the stationary fulcrum-rod m 104, and adjacent to the latter an adjustable tension-spring 109 is placed beneath the key--: lever and is supported upon the supportingbar 107. By reason of this construction a posed within-the keyboard at the front of the 1 type-carriage. Furthermore, it will be observed that by reason of the construction and mounting of parts as described the individual removal of the entire key or type-bar action is permitted, inasmuch as each type bar can be readily unhooked from its pivot 101 and likewise each key-lever and each fulcrum-link 115' disengaged from their pivotal points 104 and 117, respectively. Also a type-bar and its link 110 can be removed alone by simply unho'oking the type-bar from the pivot101 and disconnecting the link 110 from the pivot-key 111, which is carried with the pull-rod 1 12.

In connection with the mounting of the short fulcrum-links 115'of the type-action it is to be observed that the forward ends of these several links are arranged to extend slightly between the teeth of a guiding-comb 119 on the type-carriage and providing means for reventing. lateral movement of the said fuferum-links, while the latter are otherwise properly retained in place through the medium of the pivot-rod 117 and the retaining-rod 118.

Referring particularly to Fig. 7, illustrating the type-action, it will be observed that upon the epression of an individual key-lever the toggle 113-115 is straightened out, thereby providing an eas leverage upon the pull-bar 112, which is rawn straight forward. The forward pull on the bar 112 pulls upon the intermediate link 1-10, with the consequence of sharply throwing the type-bar .u ward and rearward against the front of the p aten. The arrangement described rovides for a direct pull upon each typear, and the motion starts with the longest and the easiest leverage upon the heel; of the typebar and a corresponding leverage uipon the pull-bar, thus securing the most esirable eature of a type-action'i. 43., straight pull upon each type-bar through the medium of an easy and gluick acting leverage.

While a etailed description has been given of the type-action to bring out itsrelation to the other mechanisms, the same is not specifically claimed herein, but forms the sub'ect-matter of a divisional application file May 6, 1905, Serial No. 259,228.

The letter-spacing mechanism of the machine includes a' ratchet escapement-wheel 120, Fig, 6, mounted upon a vertical pivotpost 121, supported on the horizontal portion of the base and carrying a pair of pinions 122, Fig. 4, normally meshing with the double rack-bar 123, which latter is carried upon the longitudinal rod 124 of a spring-pressed rackframe 125.

By reason of employing a air of pinions 122 and a pair of racks 123 t e same can be made coarser than those usually employed,

while at the same time securing a finer and more perfect mechanical mesh between the parts. In using two pinions and two racks the same are so arranged that the teeth of the pinions are in alternate relation, and likewise those of the racks are alternately disposed, with the result of producing a fine mesh between the pinions and the racks through the employment of coarse-toothed surfaces;

The release 'of the racks 123 from the pinions 122 is accomplished through a releaselever 126, Fig. 2, pivotally mounted, as at 127, upon one side of the type-carriage frame and carrying the cam-pin 128, moving against one end of the rod bearing the racks 123.

The release-action is referably accomplished in connection with the combination movement-controlling key 93, which is intended to provide not only for the releaseof the carriages, but also for line-spacing and for the disengagement of the ribbon1nechan ism gear, as will be presently explained.

The letter -'spac1ng mechanism also includes aspring-retracted pawl-frame 129, arranged horizontally over the base portion 1 of the machine and mounted at one end upon a horizontal pivot-rod 130, with which is associated a retracting-spring 131. The spring-retracted frame 129 carries therewith an oscillating dog-lever 132, bearing the escapement-dogs 133, and at its swinging end the said frame 129 is provided with a tread portion 134, Figs. 4 and 6, for engagement by a universal bar 135, lying beneath all of the key-levers 114 and carried by a normally spring-elevated pivoted frame 136. This universal-bar-carrying frame 1 36 lies beneath and'is depressed by an actuating-rod 137, carried by a pivotal space-key frame 138. This space-key frame supports at the front thereofthe space-key 139, lying within the front portion of the ke board, and at this oint it is to be observe that the side memers of both the universal-bar frame and the space-key frame have the same pivotal connection and mounting upon the stationary fulcrum-rod 104 as the individual key-levers 114-, although, if desired, this detail could be varied.

The line-spacing mechanism includes a spring-retracted rocking actuating-frame 140, mounted upon the center rod 17 of the pa ercarriage frame '6 and having an upstan ing lever-arm 141, Fig. 3, operating against a stud 142, projected outwardly from a springretracted slide 143, carrying a sprin -de pressed spacing-pawl 144, normally eld ust free from engagement with the ratchet feed-disk 40 by the pin 185, Fig. 4. The slide 143 is slidably mounted upon the inner sideof one of the end plates of the rollercasing 66, and the stud 142 projects through and works in the slot 145, rovided insuch end plate. The said roc ing actuatingframe 140 carries a vertically-movable bearing-M11146, over and just free from which is an engaging roller 147. carried at the upper end of a pull-rod 148, having at its lower end a rocker-armconnection 149 with the rear end. of the operating rock shaft 150, mounted beneath the base of the machineand'carrying at its front end, which is rigidly secured to the rock-shaft 150, a rocker-arm 151.

. This rocker-arm supports a spring-catch 152,

adapted to engage diflt'erent'portions ofan adjustable spacing-stop 153. The stop 153. is m the form of a rotatable disk adjusted to its set position by an adjusting-lever 154, suitably connected therewith and held" in either lever 156, loosely pivote of a }plurality of positions by the said spring-' catc Upon its periphe the sto -body is provided with projectior i 155 of diil'erent heights. -Against these rojections rests a d at one end on the rock-shaft 150 and'carrying at its opposite end a bearing-roller 158, engaged movementcontrolling key -93. The construction described provides for variable line-spacing, and upon the de ression of the said key 93 the shaft 150 is roc ed to provide ;for actuating the line-spacing mechanism for 'the roller-platen 39. Referrin more particularly to this action, it will be 0 served that when the said key 93 is depressed ressure is placed upon the roller 158, an the operatin -lever 156, bearing upon the stop 153 at t e swinging end of the rocker-arm 151, causes such arm to swing through an arc,

I thereby turning the shaft 150. This move- -ment of the shaft 150 causes the pull-rod,148

. frees the point of the pawl 144 to be drawn downward, with the consequence of rocking the frame 140 and causin the lever-arm 141 to draw. the plunger 143 ackward; Thismovement of the lunger 143 om the pin 185, whereupon the spring for the pawl presses the same into engagement with the teeth ofthe ratchet-disk 40. Thecontinued backward movement. of the plunger 143 causes the turning of the platen the space desired. I

The combination movement-controllmg key 93 is in the particular form shown somewhat in the form of the ordinary elongated oard. withineas reach and control'of the operator.

space-key and is arranged at the key This key 1s yieldingly, elevated throu h the medium of a plurality of supporting-lin S159,

privoted on the iront of-the type-carriage ame and arranged beneath the crown portion of the said key, asmaybe lalnly seen bears on the roller 1580f the operating-lever y the 156 for the line-spacing mechanism, while the other rail member 161 is loose from the body of the key 93 and has a bearing on the roller 92 of the operating-arm 91 for the gear-platform 84 ofthe ribbon mechanism.-

Therall member 160 may be made fast to the crown of the key 93, through the medium bf screws or equivalent fastenings, as plainly indicated in Fi 4 of the drawings, while the other rail mem er 161 has no direct connection with the body of the key 93, but is pref erably 186 in igs. 4 and 8, with certain of the sw nging supports 159. Hence a yielding support is t us provided forthe key-body,

while at the same time the member 161;is-

permitted to have an independent movement or carr 1a e-release pur oses.

The rai 161- is exten ed through a slot 162 in the left-hand end of the body of the key 93 and is formed at its outer end into a fingermechanism. The mounting of the rai member 161' permits the same to have a movement lnde endent of the operatin -lever 156 for the inc-spacing mechanism, w ereby by depressing thefin er-piece 163 the type- %i votally connected, as indicated at {piece 163, which lies over the end portion of" I the release-lever ,126 for the letter-s acing .carria emay 'be re eased simultaneously with t e throwing of the ribbon mechanism out of gear,while by a depression of the key 93 all three actions are simultaneously ac: complished i. a, the release of the carriages for shifting purposes, the disengagement of i the ribbon-mechanism gear, and the linespacing or feed of the paper. The parts may be. thus manipulatedwlthout requiring the hands of the operator to leave the keyboard.

' Another feature of the invention resides in the employment of a canceling and underscoring device. This in. the form' shown consists of a rock-shaft 164, Fig. 3, journaled insuitable bearings at the rear of the type-basket opening 94 and carrying at one end-a rocker-arm 165, bearing the eccentric ally-disposed pins 166 at diiferent distances, 9

from the axis of the shaft and co6perating with'the separated gear-notches 167 at the upper end of one arm of the bell-crank oper-' ating-lever 168, pivoted at its angle, as at 169, at one side of the t e-carriage frame.

and having a key 170 a jacent to the keyboard. T eelements 166 and 167 constitute what may be properly termed a mutilated gear, which serves to lengthen the leverage of mg-yoke member 187, Fig. 9, bearing a head 171, upon which are mounted in spaced relation the underscoring and cancelinglplements 172 and 173,- respectively.

'the lower-case position of the platen when the yoke member or frame 187 is swung up the underscoring element comes the'arm 165 as the rock-shaft 164 is turned toan operative position. The rock-shaft 164 isprovided with an'intermediate swing-'- into position so that by releasing the carriage's and sliding thesame manually the underscoring will be accom lished. Canceling will be effected in a simi ar manner, it being only necessary to shift the platen to its upper-case position.

, Referring more particularly to the underscoring and canceling elements 172 and 173, the same preferably consist of revolublymounted wheels, Fig. 15, the periphery of the former carrying a single raised line for underscoring urposes, and the periphery of the latter pre erably carrying a plurality of canceling characters, such as individual X X marks, separated dashes, or like characters,

which would provide for an effective obliteration of the writing without danger of mutilating the paper. I

.n connection with the o eration of the canceling and underscoring evice it is to be noted that the operator, with the ri ht hand depressing the key 170 and with the eft hand depressing the fin er-key 163 for releasing the carriages, simp y has to sweep the typethe time and eiiort required to cancel or erase a whole line of matter or any part of a line are reduced to a minimum;

From the foregoing it is thou ht that the essential features and action of t einvention will be readily understood; but it should also be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the scope of the invention or sacrificing any of the advantages thereof.
